Hoppes

The unrivaled Gun Medic "All-in-One" formula cleans the actions of firearms and leaves behind a thin layer of high performance lubrication, protecting against the most punishing corrosion. The cleanser evaporates in 60 seconds and leaves an extremely thin layer of lube. The lubricant utilizes the same technology used in jet propulsion engines and has a bio-based formula that is cold/heat resistant from -65 degrees F to 500 degrees F.
